T0 all w7wm z't may coiwern Be it lmown that 1, CARL SCHNEIDER, engineer, 21 subject of tl1e Grancl Duke of Mecklenburg-Schwerin, in Germany, residing in Plan, in the Grancl Duohy o1 Mecklenburg- Schwerin, Germany, and whose post-olfice aclclress is Plan, have inventecl ce1tain neW ancl useful Improvements in Briqueting-Presses; und I clo l1ereby declare the following to be a full, dem, und exuct description of the invention, such 21s Will enable others skilleol in tl1e art to which it appertains to make ancl usothe same, reference being l1ad to tl1e accompanying (112LW- ings, ancl to letters o1 figures oi' reference n1arked thereon, wl1ioh form a part of this specificacion.

Tl1e present invention relatos to 21 roller press 101- producing compressecl bodies 111 21 continuous operation, ancl in wl1ioh the molcls are proviclecl in the rollers.

'According to tl1e present invention polygonal rollers a1e employed wl1ich are intermittently but synchronously rotated in opposite directions; not 00th of tl1ese rollers are stationarily journaled. \Vhen tl1e rollers reach their pressing osition 21t which tl1e two halves of the mold a1e opposite to eacl1 other symmetlically so the'1r central axis, tl1e rollers are quickly pressecl against each other. In co11sequenoe tl1ereoi tho molds are compleely closed and Ehe m21- terial which, falling tl1rough the 1"eecl slot, fills tl1e molcl is actually compressecl. Eitl1er both rollers may be movecl toward each other at tl1e moment when they cease revolv- 111g, or only the one roller may be adjustable toward the seconcl roller, the latcer being stationarlly journalecl. The construotional form exempllfied in the accompanying clrawings is constructed in the latter manner.

Tl1e diagmms are sectional views.

Figure 1 shows the position at tl1e commencement of tl1e compression, ehe edges of the molcls just meeting together. Fig. 2 shows tl1e position at which ehe rollers are pressecl together. Fig. 3 shows the driving ear. b Of tl1e two rollers a 21ml b, tl1e one b is stationarily journalecl, whereas tl1e other roller a can be approachecl axially toward tl1e roller b. Bach of the rollers is 1nacle of an octagonal section and on each 01 tl1e eight snrfaces there is a half molcl. The adjustable roller a is journaled at the one encl of a toggle lever d, on the joint e of wl1lch tl1e rod f of an eccentric 0 aots. At tl1e posit1on sl1own in Fig. 1 at which tl1e Walls of the molcls just meet, the material to be compressecl is filled into tl1e mold. When tl1o rollers then revolve further anal tl1e Walls g of tl1e mold woulcl tencl to move apart, the eccentrio begins to straighten the toggle lever d, moving roller a up t0 toller b untll tl1e mold is completely closecl as 111 Fig. 2. Wl1en tl1e rollers revolve still furthe1 the roller a1s again removecl from the contact With ehe roller b by the action of the toggle and eccentric so that the compressecl body can easily fall out of the mold.

The sl1afc h of the eccentrio is couplecl to the driving gear of the 1ollers for intermii% tently rotating the latter. On the snid shaft h is furtl1er fitted, beside tl1e eccentric c 21 crank i, to Wl1icl1 is coupled a lever /l2 C011- necting with be roller Z). This lever lc is coupled to a clouble-armed lever m loosely fittecl 011 the slmft of tl1e roller b. At tl1e upper end of tl1is clouble-armed lever m is arrangecl 11 pawl n, which engages in a ratchet Wheel 0 fittecl to the roller b. T0 the oal1er arm 01 the clouble-armecl lever m is linked a rod p wl1ich is conneoted to an arm loosely fitte l 011 tl1e sl1aft of tl1o roller a und intermittently turning this roller by means of a pawl s on said arm q anal 21 ratchet wl1eel r 011 saicl roller a. The inter- 1nittentrotation of tl1e two rollers is thus a positive ancl synchronous movement.

1 claim 1. In 21 briqueting press the combination of 21 plurallty of cylinclers having recesses 011 their ciroumference, saicl cylinders arrangecl in pairs, one of tl1e cylinders 01 eaol1 pai1 movably journaled, Ehe shaft 0'E said movably journaled cylinder coupled by means of a toggle lever to 21 fixed point, an eccentrio, 21 rocl couplecl to said eccentric ancl acting on the joint of saicl toggle lever and aclaptel to graclually stretch saicl toggle lever so filmt tl1e radial Walls of saicl recesses remz1in in contact cluring the compression.

2. In 21 briqueting p1ess tl1e combination of 21 plurality 01:' cylinders l1aving recesses on tl1eir circumference, said cylinclers zuranged in pairs, one of tl1e cylinders o1 each pair movably jonrnalecl, the shaft 0f saicl movably journaled oylincler conpled by means of a, toggle lever to 21 fixed point, an eccentric, 21 rocl couplecl to saicl ecoentrio ancl acting 011 the joint of s z1id toggle l ever pression, on the shaft of said eccentricz a crank, a connecting rod coupling said crahk with a double-armed lever fitted loose 011 th6 shaft 0f the stationarily journaled roller, the far end of said double=armedlever car' rying a pawl, adapted to engage in a ratchet wheel on said stationarily journaled roller and intermittently rotate the same, at the other end 0f said double-armed lever a 0011- necting 10d coupled t0 an arm loosely fitted 011 the shaft of the other roller, 011 said arm a pawl adapted.to engage' in a ratohet Wheel 011 said roller and rotate the same intermittently and synchronously with the first rollen 3. A press of thecharacter described com prising in comb1nation a pair of cylindriforma mold carriers, means for synchronously and intermittently rotating said mold carriers, and means for pressing said cm- Gopies Qf this patent maybe obtained for five ce:nts each,

riers relatively one toward the other in the intermi s3ions of their rotary movement.

iiiVeIy pn a 1;qthe other, means to rotate said cylinders intermittently, said means comprising.aratcheton each cylinder, a. pawlcarrying arm for each cylinder with the pawls thereof respectively engaging said ratchefis, a link connecting said pawl-arms, means for oscillating5aid pawlarms t0 rotate said cylinders synchronously, and means operating in, intermissions 0f rotation'of the cylinders 130 move the same relatively t0 und fr0m 0ne anothen.
